All these facts involved i gre/atm trouble for the draughtsman, besides the irksome necessity, that for filling the drawing pen a goose quill or its equivalent had to be dipped several times into the inkstand and this the more, when the inkstand was nearly getting emptied.

Some of the inkstands hitherto known present likewise the disadvantage, that for iilling the pen, especially, if the inkstand has not been kept lilled up properly, the same repeated movement of dipping the pen will be needed, so that the ink inside of the stand is in almost constant open communication with the outside air. Besides the tine tubes through which the ink is to be Withdrawn would inevitably get choked owing to the drying up of the ink.

By this present invention all these troubles will be overcome.

The object of the invention is an airtightly shut up inkstand permitting the lilling of pens with china ink or ordinary ink without removing the stopper by simply depressing a knob. In the annexed drawing one working form of the invention is represented.

Fig. l is a central section thereof partly in view and Fig. 2 a detail part.

A receptacle a for the ink is supported by a pedestal b the foot plate c oi which is shaped like a saucer so as to receive any liquid dribbling from the receptacle. The

receptacle is also provided with an opening closed by a screw cap d with an inlaid packing washer d" so as to permit of an air tight closing, which cap will not be liable of getting loose like an ordinary cork stopper. When removing the screw cap Z the ink- Staiia mayfugelefoie sisteusediik einer; dinaryinkstandwhere thepen is dipped infV directly;

The lover valvee consists of a piece of4 rule.V berlhosefg sleeved overfaspherical swel lingy r on the rod raboveits p oiiit m the upper valve f is formed `off a rubberorfleathei washer', kept adjustably yfast betweentvvo small nuts on a threaded part of rodfjql Byy this arrangement both valves may be brought to a simultaneous fit on their seats and the rubber hose as well as the washer may be easily replaced owing to the fact that rod g can be easily withdrawn from the receptacle by pulling out the pivot pin h of a lever i hinged to said rod. The tight cut-off of the liquid at the lower valve e is e'eoted by the rubber on the spherical swelling, besides only a small play is left between the slender point m and the mouth of the conical neck.

This valve arrangement is one of the main features of the invention. Lever i swings on a pivot block secured to the stop side of the receptacle and a screw Z provided with a milled knob is carried by said lever 'Z which screw by way of adjustment is adapted to limit the play of lever i and thereby also the amount of opening of the valves. A helical spring la sleeved on said screw Z and acting against the bottom side of lever z' is adapted to keep the valves e, f pressed down on their seats. This spring 7c likewise like the valve packings e and f may be easily replaced by pulling out the pin Z1, of lever z'. If only a small play is left between the end of screw Z and receptacle a and when the knob o is pressed down, the valves will be opened only to a small amount and then only a small quantity of ink will appear at the point of cone fm, but if a large play is left, a large drop of ink will appear at the point of my. Ii however screwed down firmly lever i will be blocked keeping valves e, f tightly shut. This latter position will correspond therefore to the position for transport and oi rest as any risk of leakage through the valves is rendered impossible. The outlet of the liquid through the lower valve e is warranted by the simultaneous opening of they upper valve f ,whenever` the knob of screw Z has been pressed down, because any loss of liquid, through the lower valve'will be compensated at once by the inlet of air throughy vtheD upper valve. The outlet of.

liquid will last as longk as the pressure on the knob. In most cases a short touclrofthe knob willbe sufficient. As the` valve eis located `at thefbottorn ofthe receptacle all the ink may be withdrawn to its lastdr'op.

A ny crust of dried'ink formed atthe outlet" of the ,neck willbe removed. with safety Whenever conemis moved; so that an unob-V structed working of( the inkstand will be obtained. y y y n n y In thebottom `wall of ,the receptacle a central eircavation pis provided where all impurities contained inthe liquid may collect.

l In order tofacilitate the simultaneous use oi` inkstands containing inks of different colours theknob of screw'l may befitted with a coloured plate 0 having the sainev colour as theV liquid contained within the ink'stand. i" 'Ip -f am well aware that it is not new to build inkstands `withl ranYairtightly shut receptacle and two valves on the same valve rod sirnu1- .taneously operated by ,pressing on a knob of a lever connected to said rod and that it assures van exact adjustment 'of the outlet opening so as toyworlr at entire: satisfaction. l
